XYDiagram2D.DiagramToPoint(String, TimeSpan) Method
Converts a point's diagram coordinates into screen coordinates.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v20.1.dll
Declaration
public ControlCoordinates DiagramToPoint(
string argument,
TimeSpan value
)Public Function DiagramToPoint(
argument As String,
value As TimeSpan
) As ControlCoordinatesParameters
| Name | Type | Description |
|---|---|---|
| argument | String | The point's argument. |
| value | TimeSpan | The point's value. |
Returns
| Type | Description |
|---|---|
| ControlCoordinates | A ControlCoordinates object that contains information about the point's screen coordinates, and its associated pane. |
Remarks
Use the DiagramToPoint method, to convert a point's diagram coordinates (measured in axis units) to the screen coordinates (from the top-left window corner in pixels). For example, calling this method in the ChartControl.CustomPaint event handler allows you to obtain screen coordinates of series points, and draw custom graphics onto your chart across them.
NOTE
For the opposite conversion (of screen coordinates to diagram coordinates), use the XYDiagram2D.PointToDiagram method.
With the Radar and Polar diagram types, use the similar RadarDiagram.PointToDiagram and RadarDiagram.DiagramToPoint methods.
